What Counts as a Slideshow on Instagram?
A slideshow on Instagram is any post where viewers swipe or watch through multiple images or video clips in sequence. There are three ways to create one:
- Carousel post — up to 20 photos or videos in a single feed post (most common)
- Reels — a video slideshow with transitions, music, and effects
- Stories — a sequence of Story slides that play automatically
Each format works differently and serves a different purpose. Here's how to create all three.
Method 1: Instagram Carousel Post (Swipeable Slideshow)
This is the classic Instagram slideshow. Viewers swipe left to see each slide.
Step-by-step
- Open Instagram and tap the + button at the bottom
- Select Post
- Tap the multiple image icon (overlapping squares) on the right side
- Select up to 20 photos or videos from your camera roll
- Tap Next
- Apply filters or edit each image individually (tap a photo to edit it)
- Tap Next again
- Write your caption, add hashtags, tag people, and set your location
- Tap Share
Carousel tips
- First slide matters most — it's what appears in the feed and determines whether people swipe
- Use a consistent visual style across slides (same fonts, colors, layout)
- End with a CTA on the last slide — "Save this post," "Follow for more," or "Share with a friend"
- Mix photos and videos — carousels can contain both in any order
- Instagram carousels get higher engagement than single-image posts because the algorithm re-shows them to people who didn't swipe the first time
Carousel dimensions
| Format | Size | Aspect ratio |
|---|---|---|
| Square | 1080 x 1080 px | 1:1 |
| Portrait (recommended) | 1080 x 1350 px | 4:5 |
| Landscape | 1080 x 566 px | 1.91:1 |
All slides in a carousel must use the same aspect ratio. Portrait (4:5) takes up the most screen space in the feed and tends to perform best.
Method 2: Reels Slideshow (Video with Transitions)
Reels let you create a video slideshow with music, text overlays, and smooth transitions between photos.
Step-by-step
- Open Instagram and tap the + button
- Select Reel
- Tap the photo icon in the bottom-left to select images from your camera roll
- Select the photos you want to include
- Instagram will automatically create a slideshow from your photos with a default duration per slide
- Adjust the duration of each clip by tapping it on the timeline
- Add music from Instagram's library by tapping the music note icon
- Add text to individual clips by tapping the text button
- Add transitions between clips (swipe, fade, etc.)
- Tap Next, write your caption, and share
Reels slideshow tips
- Keep it under 30 seconds for maximum retention — even if Instagram allows up to 3 minutes
- Time transitions to the beat of the music for a polished feel
- Add text on each slide so viewers get value even without sound
- Use trending audio to boost discoverability
Method 3: Instagram Stories Slideshow
Stories play as a sequence of slides that auto-advance every few seconds.
Step-by-step
- Swipe right from the Instagram home screen or tap your profile photo
- Select a photo or video from your gallery (or take one)
- Add stickers, text, music, or drawings
- Tap Your Story to post
- Repeat for each slide — each upload becomes a new slide in your Story sequence
Stories slideshow tips
- Add music to tie the slides together — you can use one track across multiple Story slides
- Use the "Layout" option to create collage-style slides with multiple photos
- Keep text short — Stories disappear in 15 seconds per slide, so viewers need to read quickly
- Use polls, quizzes, or question stickers to make your slideshow interactive
Which Slideshow Format Should You Use?
| Goal | Best format |
|---|---|
| Educational content, tutorials, tips | Carousel |
| Aesthetic photo dump, travel content | Carousel |
| Photo montage with music | Reel |
| Product showcase with transitions | Reel |
| Behind-the-scenes, day-in-my-life | Stories |
| Quick updates for existing followers | Stories |
| Maximum reach to new audiences | Reel |
| Maximum saves and shares | Carousel |
Carousels are best for content people want to save and revisit. Reels are best for reaching new audiences. Stories are best for engaging your existing followers in real time.
How to Make Your Slideshow Stand Out
Design tips
- Use a hook on slide 1 — a question, bold statement, or curiosity gap
- Keep visual consistency — same background color, font, and layout across slides
- Use high-contrast text — make sure text is readable on both light and dark backgrounds
- Leave space for captions — don't put important text at the very bottom of 4:5 images, as it gets cut off in the feed
Engagement tips
- Ask a question in the caption to prompt comments
- Include a "save this" CTA — Instagram's algorithm weighs saves heavily
- Post at peak hours — when your audience is most active (check Insights for your specific data)
- Use 5-10 relevant hashtags — focus on niche, mid-volume hashtags rather than overly broad ones
